I won't write again what other people have said (I read all the comments and so should you)
But all I have to say is we will come back. My wife wants too and I kinda agree the place was great : very spacious for the price (particularly for Nana).
I for one actually like the old style in these condos from the 80's. And as some other people have said, they are more spacious than today condominium.
What I liked the most : it is very quiet at night. Which is amazing for Soi 4
I do think -as some other people have pointed out- that this apartment is more taken care of than other rooms in the condo. I wouldn't be surprised
Go for it, book this place !
As for us, we will come back for sure ;)
